There are many methods of shaping metals. Some methods involve cutting and grinding the metal into shape. Then there are some methods that use heat to bend the metal into shape. Each method has its own advantages. However, metal structures that require detailing cannot be cut or grinded into shape. Such pieces have to be formed using a metal casting furnace. This method melts the metal and liquefies it. The liquid metal is then poured into a die or cast. Once the metal cools down, it is removed from the die and it retains the shape. Following are few advantages of using a casting metal surface:
- Structural Detail
Grinding and cutting metals has certain limits. There are certain shapes or details that cannot be achieved using these techniques. This is where the casting technique is used. A metal casting furnace melts the metal and pours the liquid into a cast. The cast gives the metal a particular shape. The best thing about casting is the detail. The shape will be as detailed as the cast itself. Since the metal is liquefied, not a single detail will be left out.
- Strength of Casted Metal
Grinding and cutting often weakens the metal. This is why this technique cannot be used for certain types of metals. This is why they are melted in a melting furnace and then the liquid metal is molded. This technique ensures that the structure is extremely strong and doesn’t have any flaws.
- Cost of Casting
Shaping metal using cutting and grinding proves to be expensive in most cases. However, casting is quite cost-effective. It is used for making jewelry and even heavy-duty metal parts.
- Finishing of the parts
Finishing of the parts that are manufactured by casting process is not very high. It also depends on what type of casting process is used however parts must be machined in order to get high finish.
Metal casting is thought to be a modern day innovation. However, it is a very old technique that has been around for a long time and is still as effective.
